Spec I Clutches are great setups and I would honestly take one over the stage II. Why would I do that? Because the steel backed organic material is awsome because it holds up against higher heat conditions, it resists tearing and bursting from hihg RPM abuse, it has a great life span with "spirited driving".......what else can I say about steel backed organic lining??
It's better than kevlar IMO, and I would sleep better at night having a stage I over a stage II personally. The kevlar will be like normal organic lining, and won't surpass it's holding power/bite. Kevlar WILL keep your precious fidanza flywheels much safer as it bites into the metal much less
If you look at who uses kevlar clutches the very most out of anyone in the world it'd be semi trucks and tractors, mainly for the reasons I've stated. With a kevlar clutch disc you will have a much longer flywheel and pressure plate life span. You will also have a worthless non-abrassive clutch disc if any oil product comes into contact with it.
IMO, everyone who is putting more power out than it did factory should start shopping for the very best clutch for them so they know what they need and know what is overkill for their car. The clutch is one of the most important components in your car and needs some research done towards putting the right one in your car. Don't read the manufactures web site and take waht they say to be true, take it with a grain of salt. Also do your own research into materials, different setups used, ect and you will know what to get and whjat not to get.
